Few years ago I earned money from Youtube\PPD.
Yotube was one of the best ways to earn back then,but people were flagging all my videos and my earnings dropped.
My question is what is the best method nowadays to get traffic?

Youtube , Instagram but most faster revenue is from youtube. Try to find a way for them to not flagging anymore your video.
Or try to find a way to invest little and make money fast before they flagging you :)
